[Freeswitch-users] xml dialplan - regurlar expression question / Sanity Check!

[Sean Devoy]

Hey Avi,

 

Using your regex:  ^(?:1|\+1|001)?([2-9]\d\d[2-9]\d{6})$

Doesn't $1 match the stuff in the first set of () and $2 match my needed 10
digits?

 

Thanks,

Sean

Ha, that was a tricky one!

 

Here's the issue - he dialed: 1-800-336-940 -- that's too few digits!

So your optional one made it match anyway.

 

Your matching is too allowing - here's the regex I use:

 

^(?:1|\+1|001)?([2-9]\d\d[2-9]\d{6})$

 

That matches [nothing, 1, +1 or 001] prefix for USA. Then, bridge like now
to "1$1".

 

btw, if you want a separate match for USA toll-free it's:
^(?:1|\+1|001)?(8(00|55|66|77|88)[2-9]\d{6})$

 

There's also some good example on this page, the link goes directly to USA:

HI,

 

I really hope this question is not as dumb as some of my recent questions
(Anybody else wiped out you O/S lately?)!

 

Anyway,  I have an xml dial plan:

  <extension name="ten_or eleven_digiti_dial" >

    <condition field="destination_number" expression="^1?(\d{10})$">

      <action application="set" data="ringback=${us-ring}"/>

      <action application="set"
data="effective_caller_id_number=${outbound_caller_id_number}"/>

      <action application="set" data="ani=${outbound_caller_id_number}"/>

      <action application="set"
data="effective_caller_id_name=${outbound_caller_id_name}"/>

      <action application="set" data="hangup_after_bridge=true"/>

      <action application="bridge"
data="sofia/gateway/vitelity-inbound/1$1"/>

    </condition>

  </extension>

 

I thought that would accept either 10 or 11 digit numbers starting with 1
and bridge to the gateway always using 1 plus the 10 digits.

 

In fact in my log I can see:

Dialplan: sofia/external/220 at fs_bfis.bizfocused.com Regex (PASS) [ten_or
eleven_digiti_dial] destination_number(14104207777) =~ /^1?(\d{10})$/
break=on-false

Dialplan: sofia/external/220 at fs_bfis.bizfocused.com Action
set(ringback=${us-ring}) 

Dialplan: sofia/external/220 at fs_bfis.bizfocused.com Action
set(effective_caller_id_number=${outbound_caller_id_number}) 

Dialplan: sofia/external/220 at fs_bfis.bizfocused.com Action
set(ani=${outbound_caller_id_number}) 

Dialplan: sofia/external/220 at fs_bfis.bizfocused.com Action
set(effective_caller_id_name=${outbound_caller_id_name}) 

Dialplan: sofia/external/220 at fs_bfis.bizfocused.com Action
set(hangup_after_bridge=true) 

Dialplan: sofia/external/220 at fs_bfis.bizfocused.com Action
bridge(sofia/gateway/vitelity-inbound/14104207777)

 

BUT

It does not work for my customer :

Dialplan: sofia/external/101 at fs_alst.bizfocused.com Regex (PASS)
[ten_or_eleven_digiti_dial] destination_number(1800336940) =~ /^1?(\d{10})$/
break=on-false

Dialplan: sofia/external/101 at fs_alst.bizfocused.com Action
set(ringback=${us-ring}) 

Dialplan: sofia/external/101 at fs_alst.bizfocused.com Action
set(effective_caller_id_number=${outbound_caller_id_number}) 

Dialplan: sofia/external/101 at fs_alst.bizfocused.com Action
set(ani=${outbound_caller_id_number}) 

Dialplan: sofia/external/101 at fs_alst.bizfocused.com Action
set(effective_caller_id_name=${outbound_caller_id_name}) 

Dialplan: sofia/external/220 at fs_bfis.bizfocused.com Action
set(hangup_after_bridge=true) 

Dialplan: sofia/external/101 at fs_alst.bizfocused.com Action
bridge(sofia/gateway/vitelity-inbound/11800336940)  NOTE THE EXTRA LEADING 1

 

So, what am I missing?

 

Thanks,

Sean
